Brooks & Dunn lead singer walks off stage during encore, leaving fans concerned for his health

During a concert in Indianapolis on Thursday, the 71-year-old Brooks & Dunn member was singing the band's iconic hit, "Boot Scootin' Boogie" during the show's encore when, at one point, he gestured that he was done. 

He faced the audience and pounded his heart before waving and walking offstage. 

"Feel better, Ronnie!!! Thanks for giving us all you could!!" the caption of the video read. 

"Anyone know what's going on?! Hoping a quick bug, and he's back on stage tomorrow!" the caption read.

"When they were in Houston he said he was getting over Covid and strept [SIC] throat. He needs to rest and recover," one user commented on the post.  

Fans took to social media to share thoughts of encouragement and well-wishes to Dunn. 

"Praying for you Ronnie! Hope you get better soon," one fan wrote on the band's official Instagram page. 

"You guys were awesome last night in Indy!!!! My first time seeing yall and definitely was a dream well met!! It looked like you were sick near the end though and I hope you get better soon!!!!!" another wrote. 

Representatives for the band and Dunn did not immediately respond to Fox News Digital's request for comment. 

Dunn, who returned to the stage Friday night, has not addressed the exit.

Last month, he revealed that he had been battling the flu as well as strep throat.
